Seat Memory

At driver's seat, remove bolts for front vertical adjuster. Lift front end of seat cushion slightly for access to power seat ECU. Remove power seat ECU, but leave wiring harness connectors attached.
Check voltage between power seat ECU connector "B", terminals No. 7 (Yellow wire) and No. 11 (Brown wire). See Figure. With memory switch SET button pressed, battery voltage should exist. With memory switch SET button released, voltage should not exist. Check voltage between power seat ECU connector "B", terminals No. 6 (Purple wire) and No. 11 (Brown wire). With memory switch "2" button pressed, battery voltage should exist. With memory switch "2" button released, voltage should not exist. Check voltage between power seat ECU connector "B", terminals No. 5 (Pink wire) and No. 11 (Brown wire). With memory switch "1" button pressed, battery voltage should exist. With memory switch "1" button released, voltage should not exist.
If voltage is as specified, see next test listed in SYSTEM TESTS INDEX table. If voltage is not as specified, check memory switch continuity. See MEMORY SWITCH CONTINUITY table. If switch is faulty, replace switch and retest. If switch is okay, check power seat ECU and memory switch harness connectors. If connectors are okay, replace power seat ECU.
